In view of the growing load demand in developing countries, overloading in existing transmission lines is a major concern. In addition to the voltage drop due to overloading, the proliferation of non‐linear loads in recent years distort the shape of ...

Improved Harmonic Mitigation Using Dual Three-Phase iUPQC [PDF]
This study simplifies iUPQC administration by employing a dual three-phase design, which makes the methodology behind the study more transparent. By utilising a parallel (shunt) and series active filter, it is possible to limit the amount of harmonics ...

Rectifiers are required by the devices connected to the distribution end of the electrical power networks for AC/DC conversion. The line current becomes non-sinusoidal when a capacitor with a significant value is used to mitigate the output voltage ...

Geometric Algebra Power Theory (GAPoT): Revisiting Apparent Power under Non-Sinusoidal Conditions
Traditional power theories and one of their most important concepts --apparent power-- are still a source of debate and, as shown in the literature, they present several flaws that misinterpret the power-transfer phenomena under distorted grid conditions.

Effect of Side-Walls on Flapping-Wing Power-Generation: an Experimental Study
Effect of constrained flow is investigated experimentally for a flapping foil power-generator. The flow structures around and in the near wake of a flat plate placed between two side walls are captured via PIV technique with simultaneous direct force ...

Alternative definitions of energy for power meters in non-sinusoidal systems
Abstract Energy flow in sinusoidal systems is analyzed without problems by means of the traditional power definitions such as: apparent, active, and reactive, but these definitions are not properly applied in nonlinear loads. These loads present several distortions which are not correctly measured with the prevailing instruments designed for ...

Power Quality Measurement Under Non-Sinusoidal Condition
The interest on problems related to non linear devices and their influence on the systems increased considerably since 1980. This is due to the development of new power semiconductor devices and, as a consequence, the development of new converters that increment the non linearity in electric power signals substantially (Arrillaga et al., 1995). Several
